Christopher Booker, The Sunday Telegraph
When, amid all the millions of words uttered about Grenfell, are we finally going to focus on the real cause of that fire? A comment on my column last week said that “only Booker could get a link between Grenfell, the EU and global warming into a single article”. But that is precisely the point. Without those two factors, the fire could never have happened.
As I had written, all this talk about “cladding” has been looking in wholly the wrong direction. The cause of the conflagration was less to do with the “rainscreen” cladding: it was the combination of 6in of combustible Celotex insulation foam behind it with a void creating a “chimney” effect, sending the flames roaring up the building.
In 1989, after a fire in an 11-storey block in Knowsley, the Building Research Establishment was asked to devise a means that could have prevented it.
It found that this should be a new “whole system test” covering all the materials used on the outside of buildings to see how they interacted when installed together.
But in 1994 the European Commission called for a new EU-wide fire test which was exactly what the BRE had found so inadequate with existing practice: a “single burn” test applied only to each material separately.
But after 2000, when a Commons committee investigated a high-rise fire in Scotland, MPs recommended that the BRE’s “whole system test” should be adopted as the British standard, BS8414.
By 2002, however, the EU had adopted its inadequate test, incorporating it in a European standard using EN 13501. Under EU law, this became mandatory, leaving the UK’s BS 8414 as only a voluntary option.
The EU had also become obsessed with the need for better insulation of buildings to combat global warming, which became its only priority. All that mattered was the “thermal efficiency” of materials used for insulation, for which none was to prove better than the polyisocyanurate used in Celotex, the plastic chosen in 2014 for Grenfell.
Fire experts across Europe have pointed out that the lack of a proper whole system test was ignoring the risk of insulation fires, not least in Germany, where there have been more than 100.
Strangely, the maker of Celotex has stated on its website that the material used in Grenfell has been tested by the BRE as meeting fire safety requirements. But the BRE has tartly responded that this test referred to a different installation; and that “Celotex should not be claiming that their insulation product can be used generically in any other cladding system”.
Had the Grenfell installation been properly tested under BS 8414 it would not have met the standard, and thus the fire could not have happened. The ultimate irony is that China and Dubai are now adopting mandatory systems based on BS 8414. They can do this because they are not in the EU. But, because Britain is still in the EU, it cannot legally enforce the very standard which would have prevented that disaster.

This has been covered before both here and in the news media in the UK. Quite simply Mr. Brooker is wrong. While the cladding was installed in order to improve the insulation of the tower the contractors responsible deliberately decided to use the cheapest possible cladding material rather than a more expensive fire proof one. This saved the contractors roughly 5000 pounds while being a contributory factor in the deaths of more than 70 people. They also decided to save costs by not installing sprinklers which again could have slowed down the speed of the fibre allowing more people to escape.
It should be noted that this cladding material is currently banned in Germany for use on similar buildings since it is unsafe and a fire hazard. Germany is also part of the EU and has stricter regulations than the UK on insulation. So clearly it cannot be the fault of EU and climate regulations since both the UK and Germany have the same regulations.
Here is Booker’s own Telegraph reporting that the material is banned for high rise in Germany:
“The safer sheets were only £2 a square metre more expensive meaning that for an extra £5,000 the building could have been encased in a material which may have resisted the fire for longer. The cheaper version is banned from use on tall buildings in the US and Germany.”
That makes a nonsense of his claim that EU regulations forced its use in Britain.
The point, I think, is that EU regulations allow the materials used rather than they require them … you’ve put up a false straw man to argue against …
Straw man, and a rather crude one at that.
“The point, I think, is that EU regulations allow the materials “
No, Booker’s claim is that Britain wanted to but could not disallow them, because of EU. But Germany was able to prevent their use (by classifying them as flammable), so that claim is false.
The Germans had somewhat tightened their codes before the EU introduced the Directive and thus have a slightly stricter code now.
Booker is absolutely correct.
The insulating efficiency of the Celotex was deemed to be the primary concern and the EU had done nothing to address the fire safety issues. Oh! Not quite right! They had spent 13 years talking about it.
“The Germans had somewhat tightened their codes before the EU introduced the Directive and thus have a slightly stricter code now. Booker is absolutely correct.”
There is no evidence whatsoever that EU regulations prevented the UK from improving their own fire safety standards. Or that Germany somehow “snuck it by” before the EU passed a safety directive. In fact, the evidence is to the contrary: “After the 1999 blaze (in Scotland), successive governments at Westminster were urged to tighten English building regulations on fire safety, but no action was taken. While Scotland introduced a stricter regime, the story of English regulations is one of warnings being repeatedly ignored about flammable materials fitted to the outside of buildings creating a significant new fire risk. Instead of improving rules in this area, Conservative and Labour governments appeared focused on freeing companies from red tape.”
martinbrumby, why is it that Scotland, which is both part of the UK and part of the EU, could improve their fire safety standards and England could not?

I read on one of the earlier WUWT threads on this topic that a country with a stricter code that was adopted before an EU code could keep it, but that after the EU had adopted a standard, no country could adopt a stricter standard. (I hope whoever posted that comment will post a link to it.)
Roger Knights – I believe EU countries historically have been allowed to set their own fire policies, which runs counter to what Booker says. If that is incorrect, it should be documented somewhere. This article implies that UK fire safety policies were devised and are controlled within the UK, not the EU: https://www.theguardian.com/uk-news/2017/jun/14/disaster-waiting-to-happen-fire-expert-slams-uk-tower-blocks?CMP=Share_iOSApp_Other
Rubbish. Look at the films of the blaze and it is clear many of the panels fell off anyway. Why did the fire not follow the panels rather than remain with the building? Someone knew perfectly well the insulation was to blame but wanted to deflect from the environment lobby’s responsibility for the disaster.
David Cage, thanks for providing zero evidence that the environmental lobby was the cause of this disaster.
Nick, you might like to familiarise yourself with UK politics before trying to defend the global warming establishment from any blame.
Booker is correct that EN13501 is the EU Standard. There is nothing to stop individual architects and clients from specifying BS8414. The problem arises with public works which will, under single market rules, go out to EU-wide tender. There is some debate around whether the UK government is entitled to apply a stricter standard than EN13501 but since it appears that Germany does one can assume that the UK could if it chose to. It didn’t choose to and by default the contract was based on the EU standard.
There was a dearer option available which was more fire-resistant and by all means criticise K&C for not using it — assuming that they were properly advised (another possibility for consideration for the Inquiry) — but it doesn’t alter the fact that the prime purpose of that material in that cladding was to act as an insulator to save energy in order to reduce CO2 emissions to combat global warming.
Personally I have no qualms about laying 80+ deaths at the door of those fanatics who on the basis of damn all evidence insist on damaging society. Global warming is indeed killing people — just not quite in the way the warmistas would have us believe!
“Nick, you might like to familiarise yourself with UK politics”
I am reasonably familiar with UK politics. But that is not what Booker is blaming. He says:
“But, because Britain is still in the EU, it cannot legally enforce the very standard which would have prevented that disaster.”
And since Germany, and even apparently Scotland can ban this material for high-rise, that is clearly false.
The issue is the inadequate testing regulation of the EU superseded the more rigorous British test, which became voluntary.
Nick seems to be skeptical about everything except global warming.
Richard North, on his EUReferendum.com site, argues with detailed quotes and cites that once the EU had established a standard in an area, member countries couldn’t exceed it. He calls it “the occupied field doctrine.”
(My guess is that doing so would fragment the market for such products, reducing the economy of scale available to EU manufacturers, and the ease of foreign firms in marketing within the EU.)

My understanding it was a change approved by the Management Organisation and the builder. Not just the builder.
“A list of amendments to the £9.2m contract between Kensington and Chelsea Tenant Management Organisation (KCTMO) and Rydon, the builder for the refurbishment of the 24-storey tower, reveals that the saving was made after tender by fitting “cassette fix aluminium cladding in lieu of zinc cladding”.”

@ur momisugly Germinio
The point which you overlook is that Both material systems – the one specified and the one it was amended too and was used – Met the EU Standards.
EU Directives and Regulations (standards) take mandatory precedence over home-country (member state) laws and standards. To refuse to allow something which meets the EU Regulations or Standards is to be in breach of EU regulations and leads to severe penalties. Unfortunately the UK, unlike many member states, has this civil servant tendency to stick to the word of the Directive or Regulation.
Too further correct you, it was not the contractor who chose not to install a sprinkler system, it was either the Kensington and Chelsea Tenants Management organisation or the landlord, which is the Council .
It was, as Booker correctly points out, climate regulations emanating from the EU and entered into UK law which led to the ‘upgrading’ of insulation to reduce energy use and thus CO2 emissions.
It is not unreasonable to view these deaths as being caused by the belief in Climate Change in the same way that it is the cause of the significant number of winter deaths of people forced into fuel poverty through heavily increased energy costs from renewables and their subsidies.
Bizarre as it may seem the only true casualties of ‘Climate Change’ to date are those in the developed world whose deaths arise from the policies that have been introduced by politicians to ‘mitigate’ against the manufactured, man-made scare of ‘global warming’.
There are innumerable examples of where the EU and its regulations are the Cause of a Problem rather than the Solution. That is the problem when lawmaking is handed over to unelected bureaucrats and democracy ceases to be particularly relevant. The EU hands multi-millions each year to ‘Green’ organisations to advise it on, and even to draft and prepare ‘green’ policies and regulations. That sadly is the model the EU has been constructed upon and it is very similar to the one the UN wants for an unelected global government.
Climate Change is the UN’s Trojan Horse for an unelected global marxist-socialist goverment and the end of representative democracy.
These “EU regulations” did not appear from nowhere.
It’s most likely that the governments of various EU member states, including the UK, are behind them
Old England, I believe you hit the nail on the head .
I think Janice Moore deserves an acknowledgment for her insights into this subject – although criticized by those who can’t see the forest for the trees – in the WUWT blog June 18, 2017. Congrats Janice.
That is false. The contractors saved nothing, since they were paid for the materials no matter what. The council saved the money, and since they are non-profit spent it elsewhere in the residents of the borough. The decision not to fit sprinklers was the choice of the council too.
And you ignore the point – there is plenty of evidence that the problem was nit the insulation per se but the way it was installed – the chimney effect created.
So you are simply wrong. Twice.
And we should all note that despite what “the media” has reported, the actual conclusions if those investigating the fire have not been reached yet..
” there is plenty of evidence that the problem was nit the insulation per se but the way it was installed – the chimney effect created.”
Which is a standard method to achieve maximum insulation effect. However it is extremely dangerous, and the air gap behind the panels should be interrupted at regular intervals to prevent the “chimney effect”. However this is difficult and expensive to do without creating “cold bridges”, so it is usually ignored.
So, MR Know It ALL Hammond, if there were no Flames because the material was not Flammable how would the Chimney Effect have caused the fire to spread so quickly?
Not only was the Chimney effect a serious problem but it’s very lining was solid Petrol based fire accelerant.
This is a pitiful argument. In Germany these materials are certainly prohibited for high-rise buildings, but not for multi-storey housing construction or single-family houses. The problem with polystyrene is not only the flammability above certain temperatures, but also the previous encapsulation of environmentally and mutagenic flame retardants. Now, these chemicals have been replaced, but who knows? Perhaps after 20 years of environmental protection, environmental chemists are once again aware of how harmful the new flame retardant is. In addition, the combustion process is slowed down by the flame retardant, but at the cost of a frightful smoke development. In the case of a fire, the owner naturally asks himself what death he wants to die: the suffocation in the smoke or the fire death. Both are not pleasant and could be prevented with monolithic building materials. Then one could not build a high-rise no more 100 meters high, but would have to content with a little less Babylonian.
Or build as in the past, without thermal insulation.
# There is an error:
“Now, these chemicals have been replaced, but who knows?” These chemicals were, of course, replaced only in new isolations, and the old ones continued to falter. Perhaps this is the reason why in Germany the birth rate does not even equal one and a half children per woman.
If you look at the built-up meters, which go into the hundreds of millions, of the old hereditary isolation, this could even go. Perhaps as an additional reason.
Hans-Georg: thanks for your comments on the situation in Germany. In your second comment you have written ‘hereditary isolation’. Did you mean ‘traditional insulation’?
I have read that a residential tower block in Wuppertal, Germany was evacuated shortly after Grenfell so that flammable cladding could be removed.
As you should recall from the previous thread, the figure of £5000 is highly suspect. Do you have some actual data to show it’s that low? Or do you believe only what you read in month-old newpapers?
From the previous WUWT Grenfell thread:
“…it (£5000) widely (sic) reported in the UK media from outlets as diverse as the daily mail to the guardian.” Geronimo
Oh, then it must true. The media, especially in the UK, are 100% reliable and truthful. And there’s an Easter Bunny and there are fairies in the bottom of your garden.
“Do you have any evidence to back up your figure?” –Geronemo
http://c.ymcdn.com/sites/www.aspenational.org/resource/resmgr/Techical_Papers/2015_Feb_TP.pdf?hhSearchTerms=%22installation%22 “Fire rated cores are more costly and add approximately $2.00 SF to the material price.”
The building is 220 feet tall by about 66 feet in width. Total area: 58,000 sqft. Deduct 30% for windows (another problem in themselves), so roughly 40,000 sqft, times $2/SF = ~$80,000.
I know you’d rather believe the media that agree with your biases, but I’d hope you at least read the WUWT threads on this subject and the responses to questions you ask before presenting bird-cage-liner nonsense as fact. I suspect you’re merely a troll, repeating the same misinformation over and over, with no ability or interest in hearing what others say.
To clarify: as shown internally, the above comment is in response to Geronimo’s repetition of misinformation from the previous Grenfell thread.
I think you are quite wrong about the motivations of the contractors. The cladding manufacturers advise that in fact only Reynodual (which has A2 fire rating under the EU standard) should be used on buildings above 30 metres tall (about 100ft). That consists of a couple of aluminium sheets bonded together, and is about as useful as a chocolate teapot for insulation. The architects had originally specified zinc cladding, which is only slightly less good as a conductor that the aluminium you might make saucepans out of. When it came to it, the choice was between the FR and PE grades of Reynobond. The latter is twice as good an insulator as the former. Both actually have a similar rating under the EU fire standard. The fact that the PE grade is cheaper is merely a small bonus, compared with the greenie points for extra insulation. That the manufacturers advise that PE grade should only be used on buildings of up to 18 meters (with the FR grade considered suitable up to 30 metres) mattered not one jot: the EU regulations were complied with.
http://www.arconic.com/aap/north_america/catalog/pdf/specifications/ReynobondEngProperties.pdf
Nick Stokes is not correct about the situation in Germany: their harsher standard is, like the British one, only advisory, but Germans are perhaps more inclined to take advice most of the time. There are however some buildings in Germany that are clad in Reynobond PE.
Some things emerge in whole system tests that most people wouldn’t think about.
Fiberglass insulation doesn’t burn. On the other hand, installed in a stud wall, it reduces fire protection. There are two mechanisms:
1 – The fiberglass melts and a chimney forms in the stud bay allowing the fire to spread more quickly. link
2 – The fiberglass doesn’t permit the facing gypsum board to cool off. It cracks and falls off and the fiberglass doesn’t protect the studs. link An empty stud bay actually provides more fire protection than one filled with fiberglass because the gypsum board remains intact longer.
The stupid EU regulation is another reason why Brexit is a good thing.
There is much inconsistency about what exact insulation was used–some say polyethylene, some say polyurethane. Elsewhere we see fiberglass or (possibly) calsil. Are you saying there was existing fiberglass insulation within the interior wall? It’s possible.
It has been reported as Celotex which uses an expanded polyisocyanurate foam to form rigid sheets with aluminium foil cladding on both sides. It is very widely used as roofing insulation in housebuilding in the UK and typically ‘protected’ with plasterboard of sufficient thickness to provide 30 minutes fire resistance.
Polyisocyanurate foam is also becoming a more widely used material as a constituent part of SIP panels (structurally insulated panels) which orignated in Canada. These typically have OSB (Oriented Strand Board) which is structural on either side with a sandwich of PU foam between them to provide insulation. Using this system the walls and roof can be manufactured in a factory with all of the door and window cut-outs in place. A house can be erected on a prepared site in 3-4 days and then finished with external weatherproofing cladding. Some SIP panels make use of cement particle board on the exterior to allow for simple rendering as an external finish.
See https://www.celotex.co.uk/assets/health-and-safety-hands-apr15.pdf ) You will note that no specific temperature is given, it merely states ” will burn if exposed to a fire of sufficient heat and intensity.”
A data sheet showing 450 C as the initial combustion point is here https://www.dyplastproducts.com/msds-isoc1 although this may be a product with a slightly different composition to Celotex.
More information is given here :https://foursevenfive.com/reason-foam-fails-2-unacceptable-fire-hazard/
Celotex and its equivalents is a material that has been specified by architects over many years in conversions and refurbishments I have carried out. This recent disaster has led me to wonder just how safe, even with plasterboard fire barriers, the material is in domestic use. Having said that I am not aware of any domestic house fires where it has been the cause of a fire or of a fire spreading although the highly toxic gases released when it burns pose a major hazard to both occupants and fire services. I am actively looking into this at present for my own peace of mind.
There are a lot of ill-thought out building regulations which have been introduced because of ‘climate change’. One such which enforces ‘airtight’ houses have led to significant condensation problems which in turn leads to mould and spores; I have long suspected that this is a contributor to the huge increase in asthma and allergy sufferers in the UK in recent years.
I was talking about the importance of whole system tests vs. “single burn” tests. As an example I cited tests on stud walls that were done years ago by the National Research Council of Canada. Those tests produced results that would not have been inferred from just testing the individual materials.
I wasn’t talking about the specific materials or designs that were used on the Grenfell Tower. My whole point was a general one that whole system tests are necessary to predict what will happen if a fire occurs. Firefighters and construction engineers know that, apparently the EU doesn’t.
One of the drawbacks of global warming policies is that there are other priorities that are ignored. The customer with the Grenfell tower was a part of the UK government, and ultimately the customer is responsible for setting the standards of construction above and beyond simply meeting building codes, which a different branch of the UK government set.
Someone made it policy to put a priority of “energy efficiency” over sprinklering the building, or adding a second fire escape route, as well as not properly supervising the specifications of the retrofit.
Blaming greedy contractors is a popular demagogic theme, but customers who went with a low bid are also at fault.
Incompetent contractors are probably a worse problem. When I worked for the feds, there was a mechanism for disqualifying contractors who couldn’t demonstrate that they were competent. I’m guessing that those rules still exist.
I’ve seen contractors go bankrupt because they didn’t read the specification right. The government (my onetime employer) then has to pay someone to rip out the bad work and do the job right. Here’s a similar example.
Tom – I am not sure where in the process the fault lies and we need to wait for
a proper enquire before casting blame. However I think the issue is a standard engineering problem – you can do it properly or you can do it cheaply. Unfortunately this time they went with “cheaply” and people died.
What I think I failed to emphasize was the conflict of interest with one branch of the government supposedly setting standards for another branch of the government. It is not a matter of paying off the building inspectors when it is government housing.
I believe the correct contractor quote is: You can have it cheap, fast or right. Pick any two.
The mantra as I learned it: “Good, fast, cheap. Pick two.”
Tom, you’re right up to a point, but the “somebody” who made energy efficiency a priority was also the British government which, in some mad attempt to “set an example” to the rest of the world allowed a FoE activist a virtually free hand to draft a Climate Change Act which requires the UK to decarbonise at a rate faster than any other country in the world.
Add to that a requirement (almost) for local authorities to choose the lowest tender for their contracts and Grenfell Tower is where you end up, sooner or later!
The building standard is of course actually simply that imposed by the EU. Please remember that in several EU countries, the Greens are a much more potent political force: indeed, they have at times formed part of coalition governments in several of them. Here are the EU’s Green Alliance MEPs:
http://www.europarl.europa.eu/meps/en/search.html?politicalGroup=4281
From what I have seen it is a perfect example of free capitalism, delivering the cheapest material at the least expensive price. That people died, well, that is the necessary cost of the free market.
That the EU and Climate had anything to do with it, charade. But the sheeple here seem believe anything.
Hardly “free capitalism” if it was driven by governmental regulations about insulation requirements.
Fact is, there are many contributory factors, each of which could have been the cause in that the disaster might not have happened if they were not in play. For example, there have been more examples of such exploding fridges causing fires because the coolants were changed from Freons to more flammable coolants in order to save the earth/ozone layer. Environmentalism comes with a very high price tag for some unfortunate people and environmentalists are often very good at ignoring one side of the cost-benefit equation.
I fail to see any form of capitalism at work here. All parties were part of government socialist organizations who will never accept any responsibility for anything. Socailism has never worked anywhere at any time, ever.
The government is Tory which opposes socialism! The lack authority (Kensington) is dominated by the Tories. These are not socialists!
RE: “From what I have seen…..”
You should have your vision checked… and update your economics education.
A free market economy is one that organically finds the most efficient use of limited resources. This efficiency usually results in cheaper prices for the exact same material, but has nothing to do with delivering shoddy or improper material. Quite the opposite. In a true free market, delivering poor quality material will find one quickly out of business. Unfortunately, very successful companies have the power to poison the free market with crony capitalism, which isn’t really capitalism at all.
In free markets you tend to get the highest amount of quality for the price you pay. The more you pay, the better quality you get. In state-financed contrat work, it is rather the opposite, quality is not related to cost. Your typical publicly-financed infrastructure project will cost more, take longer to build, and usually be of lower quality than a privay financed and built project of a similar size. The Grenfell Tower renovation was a public project, it was was approved and financed by the state, the free market had little to do with it. Had it been a privately-owned building, most likely it could have received a much higher quality renovation for the same price the state paid.
Grenfell Tower was “Council Housing”, i e owned and managed by the local government, which also drew up the specification for the refurbishment. “Capitalism” was only involved if the contractor did not work according to the specification, but as far as I know there is no evidence for this.
Take a look here:
http://www.arconic.com/aap/north_america/catalog/pdf/specifications/ReynobondEngProperties.pdf
You will find the Reynobond PE has twice the insulation effect of Reynobond FR (and the product the manufacturer recommends for tall buildings offer no effective insulation at all – it’s just a couple of aluminium sheets bonded together.
Look at the values for “R” Thermal Resistance
Obviously false.
What about the fact that the manufacturer states that the product is not to be used above 10 meters high??? …http://www.express.co.uk/news/uk/818480/cladding-Grenfell-tower-illegal-10m-32-feet-not-to-be-used-Arconic-manufacturer-Kensington
and, “…The company advises customers in a brochure that Reynobond PE should not be used on buildings taller than 10 metres, and Grenfell Tower is 60 metres tall. …”. …http://www.cbc.ca/beta/news/world/cladding-arconic-alcoa-grenfell-fire-1.4178157
So the designer is to blame. They did do it according to a blueprint, right?
It appears the product in question is Celotex RS5000
https://www.celotex.co.uk/products/rs5000
Some notable quotes from the company’s website:
Suitable for use in warm steel frame constructions for ventilated facade applications, Celotex RS5000 can be used in buildings above 18 metres in height – a first for PIR insulation.
With low emissivity textured aluminium foil facings, Celotex RS5000 comprises rigid polyisocyanurate foam core (PIR) using a blowing agent that has low global warming potential (GWP) and zero ozone depletion potential (ODP).
Has been tested to BS 8414-2:2005, meets the requirements in BR 135 and the first PIR insulation suitable for rainscreen cladding applications above 18 metres in height.
Strange that it says “tested to BS 8414-2:2005”, but then says “meets the requirements in BR 135”.
Why does it not say “meets the requirements in BS 8414-2:2005”??
Interesting points on the standards. Celotex is now owned by a French company and although I am sure that is irrelevant it reminds me of another French company which had developed a thin quilted material for insulation but was struggling to get the insulation standards it claimed certified by an approved body. After 2 or 3 years it purchased a UK company which was able to certify and within months the product was certified.
In the “time line” I would suggest there is at least one Bureaucrat involved with connections (money and contracts) who “Regulated Up” the “Failed Specifications” knowing they were failed and garnered a “Handsome Payday … Off Books … for decades” and now is likely at or near the top level to the E.U. in Brussels.
In the E.U., old Europe and Americas, Nationalists and Racists hatreds run deep. Jus sanguinis (Latin: right of blood), and Jus soli (Latin: right of soil).
You can think of Jus sanguinis as Vampires and Jus soli as Lycans. Wars will be wars by blood or soil.
This was a colossal screw up! The most basic goal when designing and building large residential structures is to slow the spread of any fire thus affording the occupants time to exit the building. Within an hour of the fire starting, it was obvious to me that we were looking at a major fail. It was also obvious that there would be significant loss of life. I predicted ~100 from the outset.
A building that size should never have a flammable material, period
” building that size should never have a flammable material”
Portland Oregon seems not to know this:
‘A 12-story high-rise building made entirely of wood, the first of its kind in the nation, will be constructed in Portland, Oregon..’
Maybe devised by the same clever person who thought a university chemistry building should have been built from wood
“It was to be “the world’s first carbon neutral lab”, the university said, and would have housed work aimed at “fundamentally changing how we do chemistry in a more sustainable way”.
“The university’s website calls the GlaxoSmithKline Carbon Neutral Laboratory for Sustainable Chemistry as a “centre for excellence”. It says the lab is built with natural materials, powered by renewable energy and incorporating “state-of-the-art teaching and research laboratories”.”
Well they learned that in the carbon cycle , when Oxygen & Carbon get together they have dramatic chemistry…. BUT NOT ‘in a more (‘green’) sustainable way’.
And US CAFE standards cause a lot more than 70 deaths per year – but you will never hear that fact in Congress when environmental policies are debated.
Fuel efficient vehicles cause more deaths? Links to support that claim?

It is also why diesel engines were fitted to submarines. petrol leakage —> problems; diesel leakage —> rarely a problem.
Gonna have to call BS on this. The UK regulations have been calling for more insulation in walls and roofs since before the UK was in the EU.
The culprit, in my opinion, was Blair’s government who placed the onus on the landlords for fire safety, instead of allowing the fire officers to do the job.
Nice try. The applicable regulations were not the old UK set, but new ones mandated by the EU. Plus, apparently, it was decided to exceed the new regulation requirements, anticipating future amendments for even greater energy efficiency.

Mangochutney is however correct about how fire safety standards are applied. The Blair Labour government removed the statutory powers of inspections and the ability to serve improvement notices from Fire Services and created a responsibility for commercial organisations to take responsibility for fire safety standards in their buildings.
This was then delivered by a new breed of private fire safety consultants who would prepare reports on the building and any required improvements. Some of these people are very good others are not, but it should be remembered that they are acting on behalf of their employer and as a result are subject to commercial pressures that Fire Service personnel were not.
One of the issues which is likely to emerge in this case is the role of the independent fire safety consultant used by Kensington and Chelsea Tenants Management Organisation and who advised them that they did not need to show the Fire Service the report and plans he had prepared for them. Because of Blair’s change in the law it meant that the local Fire Service were not able to Require a copy of the assessment or the plans and so were unable to evaluate it themselves.
The second paragraph in its entirety in the introduction to the planning application for the Grenfell Tower refurbishment:
And later in the documents is clearly stated the requirement to get to A+ efficiency rating. Nothing could be clearer. The Planning Policy requirements in the planning application include upfront in section 3.3 (local policy):
In summary, the planning application clearly states that primary driver for the refurbishment is to reduce excessive heat loss during the winter months. Performing this work helps make a significant contribution to meeting the governments climate change CO2 emission reductions target.
Totally [snip…watch language please… -mod] insanity.
The proximate cause was the fridge explosion and fire.
Butane explodes and burns.
http://www.acr-news.com/are-our-fridges-safe
The first comment is instructive.
This was a green initiative to save the ozone layer.
So they have converted refredgerators to use butane, always thought this was a bad idea.
Thanks Lewis, I was unaware that the replacement coolant was a flammable hydrocarbon. How dumb is that.
Most of the ozone depletion came from two volcanic eruptions and attributed to CFCs. Another eco-mess portrayed as science.
This crap is killing people, it MUST STOP NOW.
it wasn’t the celotex that spread the fire.it was the polytethylene cladding. celotex doesn’t really burn.
There seems to deliberately introduced confusion about this.
nevertheless the reason for the cladding was to hide the celotex eco-insulation so the point still stands
This is not celotex as you know it. It was a foil laminated polyurethane foam board…. which burn quite strongly when the aluminum deforms from heat.
@ur momisugly Leo Smith – Celotex most certainly does burn. About 9 years ago I had to stop a contractor who was illegally burning celotex offcuts from a conversion they had carried out for me. This was on on an open fire with C14 and C16 graded timber offcuts, which as all the timber had been tanalised should not have been burned either.
Plus in this case there was an “environmetally-friendly” titanium dioxide coating on top of the aluminium, so when the fire got hot enough they probably got a nice titanium thermite reaction as well.
I disagree.
It appears that the Grenfell Towers was a concrete structure.
Concrete in itself has considerable thermal mass and in this case was probably quite adequate.
In other words the $millions spent seem to be spent on some sort of competitive insulation factor, (the global warming/sustainability factor), which very likely had little thermal effect until such time as it caught alight.
I am not a believer in standards. Although perhaps the intent is good, standards not only simply provide a minimum requirement but they most certainly do not promote common sense.

Roger,
“Not a believer in standards”? In which case you are a fool. Living in Christchurch you should
be aware of the importance of building standards for earthquakes and the deadly consequences
if they are not met. Do you check the quality of every building that you walk into or do you rely
on government standards to keep you safe? When you buy food do you test it for bacteria or
adulterants or do you rely on government standards to ensure food safety? If you go to a restaurant for dinner do you check the cleanliness of the kitchen and staff or do you rely on government standards to keep you safe? And if you drive do you check the safety features not only of your car but also the brakes of every car you might pass or again do you rely on government standards to keep you alive? I could go on and on about how standards keep you safe
and stop you being taken advantage of by other people. Standards are a vital part of modern life and have been since governments first passed laws regulating weights and measures and coinage. Commerce would be impossible without them.
Geronimo
If you believe in standards, you are the fool. Standards are routinely inappropriate, ignored, badly written, uninformed, subject to corruption, out if date, fighting the last war.
They often prevent innovation and better and safer ways if doing things since there is no incentive to go beyond them.
I eat in places where people don’t get sick, not where a government inspector in one morning has said it is safe. I fly on airlines that don’t crash and drive cars that have good safety records. But planes still crash, cars still crash, banks still crash – but they all had standards and regulations.
‘Mad Cow Disease’ occurred in the UK after a regulation forbidding cattle eating processed cattle supplements was dropped.
http://edition.cnn.com/2013/07/02/health/mad-cow-disease-fast-facts/index.html
‘Mad person disease’ main symptom is thinking all regulation is unnecessary.
Geronimo,
I love standards – there are so many to choose from
/sarc
Like most liberals, Geronimo believes that individuals are incapable of making decisions for themselves,
that all businessmen are corrupt and anyone who works for the government is perfect and incorruptible.
That’s why they believe that the only way to be safe is for government to come up with and enforce standards.
Standards are a minimum. Like minimum wage, they provide a floor for the majority of people to exceed. The problem only comes when the standards are so stringent or so specific that no one exceeds them (or even can exceed them). I have seen nonsensical building codes that require things that are neither necessary or beneficial and hamper innovation. I’ve seen standards that exist for the sole benefit of one person.
However, saying that we shouldn’t have standards is a very odd conclusion to draw from this set of facts. We need some baseline, especially in areas where bystanders are unqualified to evaluate options (such as crash test ratings, efficiency of homes, or cleanliness of restaurants).
Standards are simply attempts by governents to codify the common law.
In my city, although the earthquakes were severe, there were two multi story modern buildings which collapsed most disasterously and accounted for the majority of casualties.
More significantly, in spite of one of them – in hindsite – was found to be built grossly under spec, no one as yet has been held accountable.
Why? because the local government had inspected both buildings during construction and signed off all the tick boxes.
The mayor quickly stated publicly that whilst the city council had approved both buildings, it was a case of “all care and no responsibility”.
In actual fact the council was not competent enough to analyse the engineering standards involved and significantly neither the builder nor the design engineers nor the council have been found accountable.
It is my belief that someones head should roll – that of the council – but I believe that in a common law situation there would be more than 100 families sueing all of the above for the unneccesary death of their loved ones – meaning that all the appropriate heads would roll and there would be legal precidents that all businesses, in that sphere, would consult for ever.
A legal difficulty in cases like this under common law is that builders can hide behind bankruptcy laws and corporate veils and therefore avoid the consequences of their “misdemeanours”. Codification/ standards may have been an attempt to block this loop hole, but so far, in a number of spectacular cases in this country, it hasnt worked.
As I said above, I believe standards are simply an example of common law codification whose main function is an excuse to increase the size and authority of government for political purposes.
I did the calculations. The planning application reveals that the concrete walls had a U value of 1.5 W/m^2/K. Multiply up by the wall area of 3250sq m, and by the 8 degree difference between a 20C indoor and 12C average outdoor temperature, and you wind up with 39kW of leakage – worth around £10,000 a year at the kind of gas prices available to a block of flats with a centralised heating system. Against that they spend £2.6 million on the exterior insulation and cladding installation. A 260 year payback before maintenance and financing costs.
Green vanity gone mad.
Great answer! Cheers Roger

The severity was largely due to liquefaction.
Patrick MJD,
Although there was a lot of liquifaction during the Christchurch earthquakes, in actual fact, except the ones I have mentioned, there was not one high rise modern commercial building that actually collapsed
Engineers design earthquake resistance into modern structures where they know the building will distort and suffer significant damage – in fact enough to make them useless, but they will not collapse.
Although there was some drama during evacuation in the CBD, I am not aware of any casualties from these buildings. In fact the buildings, in that they did not kill anyone, performed to their design and engineer’s intent.
The two buildings in question, failed catestropically and were’, within seconds, little more than piles of rubble.
Both of these buildings did not peform reasonably and most certainly, neither met their statutory standards or design requirements.
Hence the result, in terms of casualties, was very similar to the one at Grenfell Towers. Very very sad.
It is a moot point indeed whether the building cladding would have reduced the heat loss and contribute to energy saving at Grenfell Tower. It would depend on external wall temperature of the composite wall before the cladding is added. An internal room temperature of 60 F (15 C) would be the room dry lining temperature also; the drop across the lining depending on thermal conductivity would be at least 30 F; further drops across thermal blocks and the concrete wall would give a drop leaving the external wall close to external ambient giving a very low C&R coefficient. Aluminium clad panels would indeed have a low emissivity but would have negligible energy saving effect because the external wall temperature would be close to ambient anyway. The cladding must have been purely decorative

Policy and Procedure (a variation of the term Standard) help us make things better. They also cause headaches. Life sucks.
Every standard should clearly state why it was put in place. Unfortunately, teaching the why’s of every standard doesn’t happen quickly. 4 inches on the edge and 6 in the field is something a guy pounding nails will understand without much challenge. It is also something an inspector will understand. 4.1 inches over the course of a project might result in some savings. 5 inches results in more savings. 4 inches has a safety factor tied to it. 5 inches may likely be plenty. 4 inches is a good place to be.
Every 20 inches IS NOT a good place to be, even though every 20 inches will work 95% of the time.
Except 95% is a bad number to quote because it isn’t tied tightly to its unit.
Not building to a standard is a really bad idea.
Not understanding why the standard is there makes the standard dangerous.
No added insulation, no fire. It’s the first box in the cause-and-effect chain.
This insulation setup was added because of the Climate Change frenzy fueled by the like of the Guardian. No time for though, it had to be done yesterday.
Chimney effect – never heard of? Never lit a stove than.
Another hasty Green blunder after diesel and bio fuel promotion.
Forrest: it very much does matter what the first ‘but for’ was. Eliminate that and the entire rest of the decision chain disappears.
A free market economy is one that organically finds the most efficient use of limited resources. This efficiency usually results in cheaper prices for the exact same material, but has nothing to do with delivering shoddy or improper material. Quite the opposite. In a true free market, delivering poor quality material will find one quickly out of business. Unfortunately, very successful companies have the power to poison the free market with crony capitalism, which isn’t really capitalism at all.

although no doubt the Standards people have been somewhat busy working out infrasound standards for their bird choppers.
Booker was apparently too busy writing his op ed piece to read the actual planning documents related to the project. From the Grenfell planning application: “The poor insulation levels and air tightness of both the walls and the windows at Grenfell Tower result in excessive heat loss during the winter months. Addressing this issue is the primary driver behind the refurbishment.”
Do the documents also mention energy efficiency, and reducing CO2 emissions? Yes, but that is well into the document, and is not stated as the primary driver, only a secondary benefit. The primary driver was to improve the thermal environment (both summer and winter) for tenants, and to help them reduce their energy bills.
https://www.carbonbrief.org/factcheck-grenfell-tower-fire-and-the-daily-mails-green-targets-claim
You appear to have a problem with English comprehension Chris. The primary driver is thermal insulation and the stated objective is meeting the governments CO2 reduction policy (section 3.3). Nothing could be clearer. Anybody who doesn’t believe can go and read the original documents. Tallbloke’s website has all the relevant links. Google it.
In other words, pull the other one Chris. The entire planning application is about “sustainable”, “renewable” etc. Not much talk about fire safety in there that I can see. The word “fire” in the safety context appears 3 times, and two of those because of mentioning the same thing twice – smoke detectors. “climate change” appears 4 times, “renewable” appears 12 times and “sustainable” appears 10 times. Its very clear to me that the whole purpose is insulation to reduce CO2 footprint. Smoke/carbon monoxide detectors are a cheap afterthought to earn the “fire safety” brownie point.
Thinking Scientist, reading comprehension issues? No, it is you who falsely have co-linked a goal of the cladding portion of the project – reducing heat loss in the winter, to benefit residents – and a secondary benefit, which is energy efficiency and CO2 impact.
First, from the planning document: “This Planning Statement is written in support of the full planning application for the “Refurbishment of existing Grenfell Tower including new external cladding and fenestration, reconfiguration of lower 4 levels to provide 7 new residential units (use class C3), replacement nursery (use class D1) and boxing club (use club D2) facilities, replacement canopy, external public realm works, redevelopment and change of use of existing garages to refuse collection area and office accommodation (use class B1).”
In other words, the project involved a whole lot more than just replacing the cladding, which you misleadingly neglected to mention. It was an upgrade to a public housing building, addressing a variety of needs that had been identified – not a CO2 reduction project. The purpose of the cladding portion of the work was 1) to reduce heat gain during the summer, 2) heat loss during the winter, 3) improve sound insulation and 4) to provide for a more attractive exterior appearance.
Less than 10% of flats in the UK have air conditioning, so clearly there is no CO2 impact to reducing heat gain in the summer. Rather, it improves comfort for the residents, just as does sound insulation, just as does reducing heat loss during the winter – especially for those on limited incomes. Only 1 of the 4 reasons for the cladding can even be equated with reducing CO2, which makes your point all the more absurd.

Chris: the part of the planning application to which you refer is concerned with the so-called Section 106 agreement. Councils are empowered to require that larger projects include an element that provides either social housing or social infrastructure, and that is the bit you are looking at. The application for the insulation, cladding, boiler replacement and window replacement and a heat exchanger on the roof for extracting heat from bathroom ventilation is here:

There is mileage in this argument. It is clear the balance of regulations are in favour of “sustainability”. The Sustainability report put insulation as ‘top priority’, the BREEAM report gve 1 point for fire safety and 37 points for various green measures. The materials used were more insulating than incombustible alternatives.
It does appear that the road to Grenfell hell was clad with green intentions
https://tallbloke.wordpress.com/2017/06/27/the-road-to-grenfell-hell-was-clad-with-green-intentions/
Most disasters could have been prevented by successive actions but looking at the film of the fire it is clear that often the cladding panels fell off intact so clearly were not the cause of the problem as the fire raged even more fiercely where they did so. At the very least this should be mainstream media information that the building Research recommendations for context dependent tests were ignored in favour of EU regulations were at the very least the cause of the rapid blaze even if other actions could have mitigated this major stupidity.
In most fields of engineering it is recognised that tests are only relevant in the context of the environment. It would appear that climate is the one exception where the scientist with their academic computer model bias and contempt for the real world dominate thinking.
Climate change is founded on failure to do proper context sensitive measurements and adjusting upwards for the errors that proper measurement show should be downwards by double the upward adjustment but this spread into engineering costs lives as the environmentalists have proved so capably in this case.
The dangers of electric cars in crashes are the next example of eco blinkered behaviour costing lives that will hit the headlines as the supercar crash showed so spectacularly.
‘film of the fire it is clear that often the cladding panels fell off intact so clearly were not the cause of the problem as the fire raged even more fiercely where they did so.’
The fire crept laterally around the building as it flared higher.
Corresponding at the time with a cladding expert the judgement was that the panels were alight.
When the panel fixing melted or failed, they then fell, sometimes flaming.
Unburnt gases from lower heated hydrocarbons reignited further up the inferno as they mixed with oxygen.
WE had a fiasco in Oz a few years ago, rooted in the same sort of moral narcissism and devoid of any real or detailed engineering or economic thought or any sort of practical implementation plan, commonly referred to as “The Pink Batts Fiasco”. Reportedly it was literally sketched out on the back of a drink coaster.
The then Labor Federal government decided that giving away free insulation batts would be a great global warming intitative by reducing the need for household heating and cooling and also would be a quick boost to the economy post GFC. Not that bad an idea I suppose in principal but then the thing went right off the rails.
Every dirtbag opportunist in the country came in to sign up. They were getting $$$ up front including for houses the owners of which did not know they had been put on the list. Massive amounts of batts were imported, cheap as chips and our local manufacturers were bypassed so went bust or ended up with huge stocks. Established installers went bust as the scum undercut them. Then untrained, unsupervised youngsters got up into roof to install said batts. About 100 houses burned down and four youngsters were burned alive says all you need to know.
Compared to Grenfell we were lucky I suppose but as you dig there is the evidence of the same old, same old green-left-mismanagerial arrogance and disconnect, especially from responsibility.
This is an old problem.
Any time a government offers a subsidy with intent of doing X there’s an incentive for the dishonest to try to lay their hands on as much of the money as possible, by ANY means possible.
With politicians, and civil servants, often being hopelessly naive to this.
Maybe they need educating in the “cobra/rat effect”.
Headline is bit over the top.
You just could say if it wasn’t for some bloke called Princip, there wouldn’t have been European Union.
With no Princip there wouldn’t have been WWI, if there was no WWI there wouldn’t have been Russion revolution, no communism, no WWII or EU, no communism no Cuban crisis, no Mao, no Vietnam War etc. etc …

I enjoyed your joke and the way you wove together all the threads but the monster Marx needs to be called out as often as possible. I’m visiting Highgate Cemetery soon to check that he’s still dead.
“Labour saving products will render many people unemployed and useless”- K. Marx.
I had to study critical tenets of Marxism as a compulsory part of the syllabus at high school and later at University. I lived in London for nearly four decades, have been to Highgate and Hampstead area numerous times and have never been tempted to visit his resting place. Coincidently there was an item on the TV last night showing the late Yuri Gagarin at the Highgate cemetery.
This all shows why an experienced judge with expertise in contracts and marine fires is needed to sort out the confusion. I hope he can endure the confected outrage about his skin colour.
I think Booker’s point, although it’s less than clear, is that the higher requirements of British Standard 8414 could have been made a contract condition in addition to the more lax British Standard Euro Norm 13501.

It seems the external composite spandrel and column cladding added little to the overall insulation of the original building envelope and that properly sealed and installed double glazing within the existing structure (rather than on the plain of the cladding) would have been almost as good.
The existing ~200mm thick precast concrete spandrel panels and new double glazed windows would typically have comparable R-values of ~0.3-0.35.
http://i.dailymail.co.uk/1/2017/06/14/20/wire-773445-1497467093-540_634x494.jpg
As the entire interior was renovated it’s a wonder that some form of inner skin incorporating an air gap to the spandrels was not considered together with the double glazing within the existing structure as insulation instead of the external cladding.
Maybe aesthetics, dressing the old building up so as not to offend the surrounding ‘nice’ residents, was an overriding consideration.
This class and race baiting is really unhelpful when emotions are high following 80 (perhaps more) needless deaths.
I have replied to that accusation but it has disappeared into the ether for some reason.
It looks like my reply has vanished for good, I’ll just say if you are going to hurl accusations like that around you could at least have the courage to do so under your full name.
Google finds me and that might embarrass people I still work with until I can retire in a few months. If you want to email me I’m happy for WUWT to send you my address. Your last sentence is pretty clear I think.
‘Maybe aesthetics, dressing the old building up so as not to offend the surrounding ‘nice’ residents, was an overriding consideration.’
As I’ve shown the local MP and her ilk are keen on the ‘Brutalist’ look so that’s very unlikely to have been a factor. She and her party have been doing all they can to start trouble, invading the council offices, attacking a volunteer because he was wearing a suit and tie, questioning the qualifications of the judge appointed to lead the enquiry because of the colour of his skin and many similar stunts.
The new Labour MP is just the sort of architecture critic who would have admired the ‘Brutalist’ aesthetic of Grenfell Tower and clamoured for the Grade ll* listing of nearby Trellick Tower.

If you look carefully at the drawing of the cladding above you’ll see, to my mind, an amazing design flaw. The insulation actually feeds under the window directly into the room. Must have been the reason for this cladding to be so deadly in this situation.
I agree, it certainly looks that way, harrowing eye witness reports describe the plastic windows failing and the walls then catching light inside the flats.
Incidentally some flats were for rent privately for about £2,000/month, hardly the slum ghetto image that some people are trying to sell.
https://www.standard.co.uk/Front/london-fire-inside-the-2k-grenfell-tower-flats-before-the-blaze-a3565416.html
IMHO the bigger design flaw is the head detailing with no rain screen cavity closure carried behind the insulation and fixed to the old structure to act as a fire break. An instant chimney to ignite the sill detail in the floor above. Polyiso foam (especially that thickness) on the vertical face acts like a kiln lining and will make the problem even worse. Temps will increase dramatically, melting the polyethylene rain screen from the inside providing even more fuel very quickly. Is it any wonder the fire spread so fast?
This is why composite testing is so important and ought to encompass closure detailing. I seriously doubt whether using a fire retardant (but still combustible) grade of rain screen would have made a workable difference with all that aluminium in the mix. Spread of flame testing in isolation tells you very little.
Nigel S:
I don’t think you like to admit to yourself how illegal subletting works. A flat with a couple of bedrooms, a bathroom and an open plan kitchen/diner/lounge may sleep as many as 10 or more. Bunk beds in each bedroom. More in the main room. £2-400pcm per head, depending on circumstances. Beds may even be time shared with those on night shift. The council rent will be much lower than the private rental you cite.
It doesn’t add up…July 11, 2017 at 5:39 pm
I’m a chartered structural/civil engineer and I’ve worked in the building industry for 40+ years (mostly conservation for the last 20+ years) and rented out property for 30+ years so I have some idea. You’ve outlined the ‘slum ghetto image’ that both political sides are pushing for their own shroud waving motives. I said ‘some flats’, it’s hardly ‘the projects’. I’m very aware of the problems of sub-letting of both private and public property.
…As the entire interior was renovated it’s a wonder that some form of inner skin incorporating an air gap to the spandrels was not considered…
That would cause disruption to the inhabitants, and reduce the living area space. External insulation does neither of these.
… and doesn’t solve the problem of a massive thermal capacity structure. What was the point of providing individual heating systems and controls with all that concrete to be heated up and diffusion in all directions? Utterly pointless and yet more potential ignition sources that have to be adequately maintained.
This is not some communal thermal store hippy cave; insulation goes on the inside, period. The renovations were extensive; losing a few square feet of floor area in the process would have been neither here nor there, something an interior designer could have easily taken care of.
The planned Zinc was replaced by Aluminium, saving some £ 200K.

Ultimately this was a failure of specifying the correct fire retardant insulation. The argument now will be about whether the standard was wrong or the insulation type specified was wrong.
I see comments that it was the plastic coating that burned. Yes it did, but 250 micron coating of plastic doesn’t burn like that, there just isn’t enough combustible material to burn with such ferocity and speed. A fireman I knew had recounted to me on several occasions when he attended fires in modern industrial warehouses made of similar plastic coated metal clad composite insulation panels. As is normal practice, they never went in to such buildings unless they knew life was in danger, because they knew just how fast such fires can spread in buildings with this type of insulation panel.
Other factors will have exacerbated the spread of the fire to so many of the flats, such as voids between the external face of the original concrete structure and gaps between windows, but such construction details, either deliberate design or inappropriate installation, are secondary to the main point.
To blame the EU’s directive on energy efficiency is a straw man, but the failure to specifically demand fire retardant insulation may well lay at the EU’s door. However, the persons who have most to fear are those that recommended to the EU legislators that this type of flammable insulation was appropriate for such a building, especially as there is plenty of evidence to indicate it is not.
This is not global warming/CO2 gone berserk, and it is disappointing to see the argument used as a stick to beat the other side of the CAGW debate (though I am more than happy to see them beaten with the right stick), because it is just this kind of half truth argument they present all the time as fact.
Lets keep this sensible please. The lessons have to be learned and all other similar structures that have been clad in the same manner now need to be rectified. That will be the real test of the State’s response to this tragedy.
